Dr. Robbins is pregnant! Jessica Capshaw and her husband, Christopher Gavigan, are expecting their fourth child together. The Grey's Anatomy actress announced the news with a sweet family photo on Saturday, Dec. 5.

"The holidays have certainly arrived…All of our lives are being added to by the lights, music and the cheer!!" Capshaw, 39, captioned the Instagram snapshot. "This year our family has reason to further broaden our smile…baby number four is on the way!! I am a lucky, lucky girl."

Capshaw posed with her husband, a co-founder of Jessica Alba's The Honest Company, and their three children — Luke, 7, Eve, 4, and Poppy, 3 — while Christmas tree shopping. The pregnant star was all smiles and kept her baby bump covered underneath a green jacket.

The Practice alum is best known for playing Dr. Arizona Robbins on ABC's Grey's Anatomy since 2009. Back in 2011, she opened up about balancing motherhood and work during an interview with Good Housekeeping.

"I love what I do and I think it shows. As my kids get older, they can see me as a mom who loves working," she said at the time. When asked what three words describe her as a parent, she replied: "Consistent, fun, [and] patient."
